Improvement in bayonet attachments



UNITED STATES VILLIAM HOFFMAN, OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT IN BAYONET A'TTACHMENTS.

Specification forming part of Letters Patent No. 47,303, dated April 1P, 19,65.

To aZZ whom it may concern:

Be it known that I, WILLIAM HOFFMAN, of the United States Army, now resident in the city of Washington, District of Columbia, have invented an improvement on the bayonet-scabba-rd frog or bayonet-scabbard attachment invented by me, and for which Letters Patent of the United States were granted on the Sth day of May,1860; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in making the bolt which secures the ear A B O, Figures l, 2, and 3, of the frog to the loop a half-cylinder, E, instead of a whole one, and the opening or hole in the plate F Gr or shield throughV which the bolt passes an incomplete circle having at its lower limit a small sector, 1), projecting within from the circumference. By this arrangement the scabbard will be permitted to revolve only about eighty degrees forward and back, thus preventing the loss of the bayonet from the scabbard, asis sometimes tl e case when the scabbard makes a complete revolution; or the same effect may be produced by using the ordinarybolt, Fig. No. 2, having on its head F at the end of its horizontal diameter D and H a short projection, and upon the plate or shield D E a pin, I, in-

serted on or near a vertical line from its center H at a distance equal to the radius of the bol thead, which pin, by coming in contact with the projections on the bolt-head, will prevent the scabbard from revolving abot'e the horizontal line on either side` As a combination of .the two modes above desciibed, the head ofthe bolt D, Fig. 3, may

be made a haltcirele, the diameter of which,

coming in contact with the pin E, inserted in the plate above, will prevent the scabbard t i from revolving either way farther than is desirable. j

What I claim as my invention, and desire to secure by Letters Patent, is

The form above described of the bolt and plate making part of the frog or attachment, which prevents the scabbard from revolving above the horizontal line on either side.

WILLIAM HOFFMAN.
